Subject: [Thuban-list] Thuban 0.9.0 released
Message-ID: <6qr82zpfbk.fsf@salmakis.intevation.de>


======================================================================
    Thuban 0.9.0 Released
======================================================================

Download: 
http://thuban.intevation.org/download.html

Overview of changes since 0.8.1:

 - Initial version of the User's Manual. This is only distributed in the
   source archives at the moment and there only in the form of the XML
   sources and images. The binaries do not contain the manual yet. You
   can read it online though:
   http://thuban.intevation.org/documentation.html

 - New Translations: German, Italian and Russian. Only the German one is
   up to date, though, as the others are based on older Thuban versions.
   For 1.0 we intend to have a translation period where all translations
   can be brought up to date.

 - PostGIS support. This feaure is still a bit experimental at this
   point and is not very well tested yet. It should work PostgreSQL
   7.2.1 and postgis 0.7 as that's what we tested it with. Newer
   versions probably also work.

For more details see the NEWS file in the sources or
http://thuban.intevation.org/changelog.html

Thanks to everyone who helped make this release possible.

Message-ID: <20030903073421.GA32060@intevation.de>

Hi,

I just uploaded pdf and online versions of the new
version of the Thuban User's Manual (1.0pre2).

Basically, there is just a new, brief chapter on how
to use and implement Extensions for Thuban.

the guess is true: See page 23 of file PROJ.4.3.ps.

The projects.h file is installed into the public include
directories. If it shouldn't be used anymore, it shouldn't be
installed also.
Thus, proj installation procedure should be adapted accordingly.

Jan / Bernhard,

I am not in a position to update the old PROJ documentation so I can't change
references in it.  Hopefully at some point we will have comprehensive new
documentation.  The pj_init.3 man page *has* been updated to describe the
modern approach.

In the meantime, as I mentioned, applications should just use proj_api.h
unless they need some internal information available in projects.h.  I will
continue to install projects.h by default in order to provide backwards
compatibility for applications setup to use the traditional PROJ include file.

Best regards,

You are right. I did not had a look into this man page.
Maybe it should be referenced under "SEE ALSO" on the proj manpage.

Subject: [Thuban-list] Extension for Import of Geonet Names Server
Message-ID: <20030910131341.GA12326@intevation.de>

Hi,

I checked a import tool for Geonet Names Server
datafiles (http://www.nima.mil/gns/html/)
into CVS.

It is an extension, and you can activate with
adding the line

import Extensions.gns2shp.gns2shp

to your file ~/.thuban/thubanstart.py

Currently it converts all the data and displays them.
This could take quite some time for the larger datasets.
It would be helpful to add a simple dialog that
asks for some type of locations to import in order
to reduce the number. Spatial selection (all points
within a selected polygon) would be interesting as well).
Any volunteers ? :-)

More about how to activate an Extension can be found here:
	http://thuban.intevation.org/doc/users_manual_for_thuban_1.0/html/c594.html

Best

	Jan

well, first of all you found a bug ;-)
If fixed it in CVS a minute ago.
In simple_command.py just import Tool from viewport, not from view
(line 19).

Furthermore, for simple_tool I recommed to use the alternative
to leave the files where they are and extend the PYTHONPATH
instead to cover the directory Examples/simple_extensions

Now it should work.

Thanks for finding this problem!

adding a new command to the registry is the only way?

The context as such is only used for the commands. Tools are activated
through commands as shown in the simple_tool.py example so getting hold
of the context shouldn't be a problem.

In the tool object itself you can use self.view if you need to access
the map window the tool is operating on. That self.view is the same as
context.mainwindow.canvas.

Subject: [Thuban-list] Ann: Experimental import of ArcView APR-Files
Message-ID: <20030922120037.GA1416@intevation.de>

Hi,

I just checked in an initial import-method for ArcView
project files (apr-files).
It is implemented as an Extension and it is experimental.
However, someone prepared a sample for the Iceland data which
proves the import works in principle.

Personally, I do not have an ArcView license and therefore
I just worked blindly on the reverse engeneering.

If anyone is out there who is interested in making the
import smoother and has both, ArcView and Thuban running on
his desktop, I would be happy to know.

I wonder whether Thuban should always call
wxInitAllImageHandlers() at startup to make JPEG and
other formats available for wxBitmap.

Any particular reason why this should better not be done?

Subject: [Thuban-list] Experimental WMS Layer
Message-ID: <20030923080002.GB3057@intevation.de>

Hi,

I've successfully implemented an Extension that adds
a Layer as delivered by a WMS Server (e.g. UMN MapServer).
It is not yet committed to CVS because I needed
to add a special renderer into Thuban main.

I think it would be a nice idea to introduce an abstraction
for rendering in a way that an extension can add its own.
How much work would that mean?

Subject: [Thuban-list] Status and Roadmap towards 1.0
Message-ID: <20030923120123.GA3603@intevation.de>

Hi,

I've shifted the release schedule by one month so that
the 1.0rc1 is planned for 20-October-2003. From there
on, no further delays are to be expected for the roadmap.

We'll spend the exta 4-weeks on further testing (external
feedback was low so far, perhaps due to holiday time), some bugs,
performance analysis/tunings and a small number of little
but helpful features which add benefit to the 1.0 release.

Furtermore, I've added WMS Layer support to the feature list
of 1.2 - an experimental(!) support as Extension will probably
available much earlier (runs for me :-).

I've removed CSV tables as data source from the 1.0 feature list.
The Table-View can create CSVs, but loading them appears not to
be of much helps since you don't have the field types.

One of the little additional features, also submitted as a wish to
the bug-tracker, will be the support of EPSG for projections.
This will also simplify the WMS Layer support.

Hi,

I've inserted a special projection into ~/.thuban/user.proj
which makes Thuban through

| Exception exceptions.AttributeError: <exceptions.AttributeError instance at 0x10ac7018> in  ignored

The projection origintates from the epsg file of the proj package.
I wrote a small converter to produce a Thuban .proj file from the epsg
file. However, at least for this projection (user.proj is attached)
I get an exception when opening the Map Projection dialog.

That user.proj contains an empty projectionlist and AFAICT Thuban
(current CVS) doesn't have any problems with it.

Well, proj doesn't like the parameters:
proj +proj=omerc +lat_0=46.952405556 +lonc=7.439583333 +alpha=90.000000000 +k=1.000000000 +x_0=2600000.000 +y_0=1200000.000 +ellps=bessel units=m
Rel. 4.4.5, 9 January 2002

That Thuban doesn't give you a better error message is obviously a bug
in Thuban. I filed a new bug report for it:

Dear list,

I recently updated thuban from CVS and I would like to use gdal for
displaying rasters.
What do I have to add, that thuban recognises my gdal-installation? It
lives in /usr/local/lib/.
But the About-Section does not find it...

Thanks for your hints.

Cheers

For gdal support to work, thuban has to be able to import the python
gdal bindings and the thuban specific gdalwarp module. You may have to
recompile Thuban for the latter to become available.

Thanks for your answer.
The "make install" from gdal installed the python_modules in 
	/usr/lib/python2.2/site-packages/gdal
After that I did a 
	python setup.py install_local
in the thuban-src-dir.
After launching "thuban-src-dir/thuban.py" gdal is still not available.

Is there a needed switch to recompile for gdal-support ?
Thank you

  Stephan Holl

Were there any error messages during the build? Do you have a file
gdalwarp.so in Lib/? Can you import gdalwarp? One way to test the latter
would be to do

   cd Lib; python -c "import gdalwarp"

Maybe you have to put the directory containg the gdal library into the
LD_LIBRARY_PATH

No, there were no errors during build, but when I try to load it
manually...

~/cvs/thuban/Lib > python -c "import gdalwarp"
Traceback (most recent call last):
  File "<string>", line 1, in ?

That is the resulting error-message. I am no python expert, so do not
know what to do...

Thanks for your help

This looks like some library was missing when linking gdalwarp.so.
According to google this is probably because gdalwarp.cpp is compiled as
c++ but linked by gcc which doesn't automatically include libstdc++. We
don't have problem because we still mostly use gcc 2.95.

This seems to be a bug in distutils in Python < 2.3. There doesn't seem
to be an easy fix, unfortunately, but there are several options:

 - Use the distutils from Python 2.3 which automatically use the c++
   compiler for linking extensions written in C++

   I just tried this by creating a symbolic link to the directory
   containing distutils in the thuban source directory and then running
   the setup.py script normally (after removing the build subdirectory
   to make sure everything is rebuilt properly)

   ln -s path/to/python/lib/python2.3/distutils/ .
   rm -r build/
   python2.2 setup.py build

   This works for me but all I can easily check is it does indeed call
   the c++ compiler. I don't have a system with gcc 3.0 where all the
   other stuff Thuban requires is already available. The distutils of
   Python 2.3 work fine with Python 2.2 apparently.

 - Do the link step of gdalwarp manually by copying the commandline
   printed by setup.py and replacing the gcc with g++

 - Add "stdc++" to the libraries list in the Extension call for
   Lib.gdalwarp in setup.py (line 1089 or thereabouts)

thuban doesn't have a dialog for proj=omerc. there is only one for
tmerc. when i changed from omerc to tmerc (ignoring what that really
means) i didn't get the exception.
